Default clutch master cylinder install

2001 installing a new gm clutch master cylinder with reservoir and line. Unit is pre charged with fluid and bled. My question is does this entire part go in assembled or do i need to remove hydraulic line from front of m/s.

I would think it connects at the joint about half way between the MS and slave cylinder. Pic?

Not sure about the gm master. I've got a tick master in mine now.

It's a lot easier to do with the driver fender removed. Here's a pic of where it goes and how it looks from the side which might help

Ignore my accusump mount.

Assembled.

There is a quick connect coupler on the frame next to the driver side pre-cat. That’s where the line from the clutch master connects to the slave tubing segment.

You'll have to fight with the hard line when you remove the old one, and install the new one. It'll get hung up and require a bunch of finagling, so just plan to be patient.

We did this job over the weekend.

Pull the driver seat out, remove the clip retaining the master cylinder pushrod to the pedal
Release the quick disconnect between the master and slave cylinder
You may have to adjust the line to twist the slave cylinder. It twists and once lined up pull forward off the firewall. A 2nd person maybe helpful watching the master from inside the car.

Installation is the reverse, We tried to keep reservoir propped up on the wheel well but have some paper towels or rags near by. The windshield washer reservoir was out of the car for other worker but may get in the way of removal and installation. Removing the splash guard as shown with the Tick install above might help as you can get eyes on the firewall better and is relatively easy to take on and off.

We have not driven the car yet. We will have to bleed the assembly as the slave is dry on the car, we were working on. We changed the clutch.

As always if you change the clutch and have not done so yet, buy a remote bleeder from Tick, Katech etc.
